Those lullabies are going to beautiful.

Home and Away actress Erika Heynatz has just shared on social media that she is expecting her first child, with husband of eight years, Andrew Kingston.

In one of our favourite celebrity baby reveals to date, the pair made the announcement on Heynatz’s instagram page in a very unique way.

Take a look.

In case you don’t have your glasses on, the 39-year-old former Australia’s Next Top model host wrote to her 15,000 followers: “Bursting with excitement to share that a beautiful little Sagittarius baby is coming our way!! Due to pop out in December unless he/she has other plans. #wearefamily.”

With names like Sonny, Ripley and Rocket Zot circulating the Aussie celebrity pack, we can’t wait to hear what Erica and Andrew have up their sleeves.

Congratulations to the happy couple.

Spoiler alert (well, maybe): Will Erika’s baby news be written into her storyline on Home and Away? Could Summer Bay’s new biology teacher, Charlotte King, be hiding a pregnancy?
